Change processor affinity program

We will cover two ways. The first way to find out your CPU thread count is with the nproc command. This command gives out a raw number of processors that are available for your Linux system to utilize. To run the nproc command to determine how many threads you have available, you must open up a terminal window. The number is the thread virtual cores count of your Linux system.

To save this information for later, do the following. It is called CPU Info. First, ensure you have a terminal window open. Then, enter the installation commands below that correspond with the Linux operating system you use. In other words, those it can be scheduled to run on. ProcessorAffinity represents each processor as a bit. Bit 0 represents processor one, bit 1 represents processor two, and so on. The following table shows a subset of the possible ProcessorAffinity for a four-processor system.

You can also specify the single, preferred processor for a thread by setting the IdealProcessor property. A process thread can migrate from processor to processor, with each migration reloading the processor cache.

Now usually when an application runs using all the cores available in the CPU then you might notice the system slowing down. By assigning the affinity for the corresponding program, it will only utilize the selected cores thus allowing space for other programs to run properly and smoothly. It will not only increase the performance of your system but also the speed and working of the programs.

Right click on the Taskbar and from there, select Task Manager. After this, the Task manager window will open. Now on Windows 7 , you need to select the Processes tab. All you have to do is right-click on the required program and then select Set Affinity. While on Windows 8, 8. With this i am able to play it again. Hey Im trying to set the affinity for system shock 2 on window 7 but when ever i try i am told that access is denied…anyone have any idea why? I see lots of times poeple with the same problems.

Im the administrator, how can I not have access? OP is Windows 7. Since moving to Windows 7 it is quite smooth on dual processor but not as smooth as it was on one processor on XP, however I cant try on Win 7 As I get access denied.

It won't let me set my processor affinity in Windows 7. Anyone have a fix for this? Having done that and eliminated the big bottleneck, there might then be some small benefit to be had from limiting each process to one core and leaving two others free, but probably not much.
